A new federal report said inmates at the Marion County Jail in Indianapolis were more likely to be sexually abused by guards than inmates at any other jail in the nation.

The Justice department report said the Marion County Jail "had the highest reported rate of staff sexual misconduct" among 233 state and federal prisons, 358 local jails and 15 special correctional facilities.

The Indianapolis Star reported that Indianapolis' jail had a 7.7 percent rate of sexual misconduct, while the average for all jails surveyed was 1.8 percent.

All of the facilities were reviewed from February 2011 to May 2012.

Marion County Sheriff's Office attorney Kevin Murray questioned the report's sample size and said he's received no complaints about sexual abuse during the period the survey was taken.
